, To all whom it may concern Be it known that I, NATHAN LOUIS SHATEN, acitizen of the United States, residing at Philadelphia,- county ofPhiladelphia, and State of Pennsylvania, have invented a new and usefulImprovement in Heaters and Ventilators for Automobiles, of which thefollowing is a full, clear, and exact description, reference being hadto the accompanying drawings, which form a part of this specification.

The object of my invention is to provide a new and improved heater forautomobiles, so constructed that the maximum amount of heat may beobtained and also so constructon the engine, and to so construct theheater that the heat may be divided between various parts of the carbody or delivered entirely to any one portion with equal effectiveness.

A further object of my invention is to provide a water jacket about theexhaust pipe, the water being adapted to transmit the heat to the bodyheating medium, air, and

' to provide meanswhereby any pressure in the water jacket will beautomatically relieved and the jacket maintained constantly full ofwater.

A preferred embodiment of my invention is shown in the drawings, inwhich' Figure 1 is a side elevation showing my heater, with water supplyand pressure relief, attached to an automobile.

Fig. 2 is a plan view of Fig. 1.

Fig. 3 is a longitudinal view in section of the heater.

Fig. 4 is a cross sectional view through the line 44, Fig. 3.

Fastened to the chassis or, is the motor exhaust-pipe b. d is a wormshaped corrugated pipe having the tubes 15 passing diametrically th ughits walls, branching off from the main exhaust pipe and having the valve6 at the point of branching, adapted to permit or prevent, the passageof the exhaust through the branch pipe. The branch pipe reunites withthe main exhaust pipe ahead of the conventional mufiier f. Surroundingthe branch pipe d is chamber 9 contact with the chamber g-to contactwith the outer walls of the chamber 72.. Across the chamber h are placedthe perforated partitions 9', 7c and Z covered by screens and adapted tobe partially or wholly closed by the revoluble gates 3', 7c, and Z. Inthe bottom of the chamber h are the air inlets m, n, and 0 protected bythe removable screens 10, 11 and 12. The inlets m and 0 have the hingedcovers p while the inlet has the casing g depending from it and dividedby a downward extension 13 of the partition is.

The chamber h is suitably connected near its forward end to the radiatorr and at its rear end to the radiator s. In both radiators are suitablydisposed the curved partitions t adapted to distribute the heat over theentire discharge surface thereof.

The lower portion of the chamber is connected at the forward end to thebottom of the conventional radiator u of an automobile, by means of thepipe 41 having therein the check valve 'w permitting water to flow fromthe radiator into the chamber 9 but not in the reverse direction, andthe shut-off valve 02 adapted for use when the heater is not, used. Thetop of the chamber 9 is suitably connected to the top ofthe radiator uby means of the pipe 3 having near the top thereof the relief valve aadapted to be set to relieve a predetermined pressure 1n the chamber 9.

In practice the chamber 9 is filled with and the valve e15 et topermitthe exhaust to the branch pipe di The relief valve 2 is set to.open 'at a pressure of one pound, andL-thegatek is closed. The

automobile is nowstarted and-operated in the usual manner. The exhaustof the engine passes through the spirally corrugated piped and heats thewater in the chamber 9;

- Air enters the' air inlet casing .qand is dividedby the downwardextension 13 f the partition 70, part of the air' being sent toward theforward end. of the chamber h and part being sent to the rear thereof.-Thea'ir'pa'sses to the front and rear of the chamber about the spirals iand z" The heat g of the exhaust' is extracted by the waterin thechamber 9 and "the heat of the water is in turn extracted-by the 'airwhich is hpated in its passage-through the chamber h. v

, oughly When theai'rreaches the forward and rear ends of the airchamberithas become thorheated and passes through the screenedpartitions j and Z into the radiators r and s respectively where it isdivided by the curved partitions t and is evenly distributed into thecar body. The air before reaching the car body is thoroughly cleaned y"and Z. v

Should apressure'of. one pound be devel- "by the'screen 11 and thescreened partitions {oped in the chamber 9 the relief valve 2 openandthe pressure relieved, and steam or water will pass into the engineradiator As the pressure is relieved a certain" amount of water will"be; lost fro'mithe chamber'fg' and "the' level ofthej w'ater thereinwill be lower thanin' the radiator. Hence as soon as thepressure isrelieved, the check valve.

will permit the :water to flow from the ,vity anddoes not to a level.-

The chamber radiatorinto the chamber '9 and again come Ifnitting more orless cold air. into the heated. fill and cooling it. Should it bedesired to heat oply one port1on o f the car body, let us say the rear,the gate 9' atthe forward end of the chamber h -1S closed and the gate kopened. Thus all the heated air goesthrough partition Z intothe'radiator s. The front part of the car body can be made to receiveall the heat by d N, the gate Z and openingthe gate k an 7 a If it isdesired to use the device as a ventilator, the gates 7" or Z, or both,are closed and the hinged cover 1 on either or both of the inlets m ando areopened. I It is self. evident that either end of the car body maybe ventilated while the'opposite end is heated, without distu'rbingin.any way the operation of the heater.

During the season when no he at" is 're=-. quired the valve e may beclosed and the exhaust prevented from pas's'lng-throu hthen heater. Theshut-off valve w is clos and thewater drained from, the heater by thevalve 14. The entire heaterm'ay then-be amount of ventilation controlledin a manfier similar to the method of controlling the eat.

Having nowfully described my invention, what I claim and desire to tersPatent 'is v v L- In a heater for automobiles, the combination with agas "exhaust pipe, of a water said pipe, a" water reservoir an inflowpipe connecting the reservoir and the water chamber, a check valvenormallyclose'd', but adapted to permit the water, in'seekin'g' itslevel, to flow from the reservoirto the-wausedas a ventilator forthe-car body and the v protect by Let- I chamber and anvair chambersurrounding ter chamber, an outflow-pipe eommunicating with the waterchamber, and an automatic release valve in said outflow pipe,'-normallyclosed, but adapted to open to relievea predetermined pressure insaidwater chamber.-
